Chapter 565 Vacuum Electron Beam Welding Technology

For Vorontsov, it would certainly be better if he could establish a joint venture with Torch Group like CB Ferrari, but he could also accept continuing to trade technology for technology.

So he nodded, indicating that he approved the cooperation method proposed by Chang Haonan:

"So, what exchange conditions are Mr. Chang prepared to offer this time?"

Chang Haonan didn't waste much time and stated his request directly:

"I heard that at the Kazan Aviation Factory, there is a vacuum electron beam welding production line, which is the key technology and equipment provided by the Kolomna Factory?"

Vorontsov was stunned, probably not expecting that the other party would know these details so clearly.

"Yes, but that production line has not been put into use since 91, so it is in average condition now. More importantly, many of the relevant technical staff have transferred jobs or even left completely."

Kolomna's vacuum electron beam welding production line is used to weld large-size titanium alloys or lithium aluminum alloys.

Specifically in the Soviet era, only the central main spar of the Tu-160 and An-124/225 could be used.

After the alliance disintegrated, no new aircraft were built for these three models, and the few aircraft that rolled off the assembly line were assembled using existing parts.

As a result, the production line naturally fell into disuse.

But what Chang Haonan wanted was not that production line.

The manufacturing and installation of vacuum electron beam welding equipment are extremely complex, and it is difficult to dismantle them, transport them thousands of miles to China, and then reinstall them.

So, it’s better to consider just building a new one.

Even if Tu 160 is not available, this thing will be useful in the future.

In the original timeline, the equipment of the Kazan factory was reactivated after not being abandoned for many years.

First, he changed his career directly and used it to produce some pressure vessels, such as rocket fuel tanks.

Later, I managed to survive until Tu 160M resumed production, and then returned to my old business.

"It doesn't matter, as long as the technical information is there."

Chang Haonan waved his hand and said it didn't matter:

"We have cooperated so many times and are considered old friends. It doesn't hurt if I suffer a little loss this time."

After two projects, Project No. 11 and the multi-arc ion plating production line, Shengjing has cultivated a group of talents who are familiar with Soviet technology and understand Russian.

Furthermore, the Torch Group is developing rapidly now. Even if there are some technical obstacles that need to be re-addressed, it should not be a waste of time.

Vorontsov said to you that you are very kind. If you really want to talk about these two technologies, they cannot be considered to be of the same level.

Of course Chang Haonan also knows this.

But since he would make this request, he had already planned it.

So he saw exactly when Vorontsov was about to speak and pushed back his words first:

"Of course, just such an exchange is still a little unfair."

"So, we are also prepared to show some new sincerity."

Vorontsov was a little uncomfortable when he choked on his words, but it was hard to show it at this time, so he had to signal Chang Haonan to continue.

"Mr. Vorontsov should have heard of our group's TORCH Multiphysics software?"

The other person nodded.

After contacting 601 during Project 3, Sukhoi quickly introduced this numerical calculation software, and was pleasantly surprised to find that it had a very high degree of matching with the modeling software KOMPAS-D they developed.

"In fact, we are developing a version with more features and stronger capabilities, and the current plan is to only provide it to a small number of users who have a deep relationship with our group."

"The only regret is that because this new version of the algorithm is quite special, it runs very inefficiently on ordinary supercomputers..."

"Fortunately, we and Sugon Group have developed new equipment specifically for these special algorithms, namely Sugon-T series computers, which can solve this problem to a certain extent and achieve high-precision, high-efficiency, and multi-degree-of-freedom calculations..."

"..."

The so-called new version mentioned by Chang Haonan is naturally the software and hardware bundling sales strategy that he discussed with Academician Li Jie at the National Science and Technology Awards dinner.

But when he said it in a different way, it became a bargaining chip.

What is making cards in the void.jpg

Although Vorontsov on the opposite side has had a lot of dealings with Chinese people, he still clearly lacks resistance to this kind of rhetoric.

After thinking about it for a while, he tentatively agreed to this exchange condition.

Of course, he can only be regarded as a middleman, and in the end, formal signature authorization from the Kolomna factory is required.

However, judging from past experience, projects approved by import and export companies are rarely rejected.

So, basically they are inseparable.

……

After ending the PY transaction with Vorontsov, Chang Haonan returned to the workshop.

The technicians from the brother units are still surrounding the multi-arc ion plating production line, discussing it with each other.

Seeing Chang Haonan reappear, everyone stepped forward and surrounded him.

"Mr. Chang, we just discussed it and now we have a proposal. I would like to hear your opinion."

One of the older ones became the speaker and said to Chang Haonan:

"I heard from Mr. Zhong Shihong that this production line will not be scheduled for formal mass production in Liming Factory for a while. At present, it will only carry out some technical adaptation work."

"It just so happens that several of our companies have projects that urgently need this kind of high-stability coating technology, and we really can't wait until the subsequent production lines are completed and put into production."

"So, during this period, can we pay for it and let Liming Factory help us produce some samples in the form of an order, which can at least be used for testing?"

Those who can stand here are all veteran comrades with certain experience in the military industry system.

From the acceptance process just now, it is not difficult for everyone to see that although Chang Haonan is not technically from Liming Factory, he has absolute say.

As long as he nodded, it wouldn't be a big problem.

After all, this production line is completely prepared for the turbofan 10 project.

It will still take some time before the turbofan 10 is finalized and transferred to mass production, or even small batch trial production.

"It's okay, that's fine."

Chang Haonan agreed to the other party's request after some thought.

Anyway, workers at Liming Factory also need to familiarize themselves with the production line. Instead of letting them practice with unused parts directly, they might as well help their brother units solve some practical problems.

But then, he added:

"However, multi-arc ion plating is not a universal process. Please report the type of workpiece and coating material that need to be coated and let the engineers here review it. If it passes, you can just place the order directly after you go back."

"It's easy to say, we are just preparing to chromium plate the inner bore of the gun barrel, which is the most common coating requirement..."

The old engineer who just spoke said immediately.

It seems that he should be from the Ordnance Industry Group.

"We are making gears for a transmission. The coating is the same as the demonstration just now, which is titanium nitride, but it does not require such a high binding energy..."

"Aviation resin glass needs to be plated with indium tin oxide on the surface..."

"Engine piston, molybdenum disulfide plated..."

The sounds of people everywhere made Chang Haonan feel a little dizzy for a moment. It took him a while to finally send these overly enthusiastic and excited technicians to the section chief responsible for this ion plating production line for docking.

However, he did not leave the workshop immediately. Instead, he quietly watched from the side as the number of projects listed on the paper increased little by little.

Then put on the other side.

Put on a new piece of paper...

Probably, this is the scene that I expected to see when I was just reborn.
